Aurélien Pupier created CAMEL-22988:
---------------------------------------

             Summary: Camel JBang eval command cannot work without camel cli installed
                 Key: CAMEL-22988
                 URL: https://issues.apache.org/jira/browse/CAMEL-22988
             Project: Camel
          Issue Type: Bug
          Components: camel-jbang
    Affects Versions: 4.18.0
            Reporter: Aurélien Pupier


in case the camel cli has not been installed, the eval command is not working. Even the tests are failing. it can happen when user is relying on jbang directly
